The following Test Examples illustrate the effects of the fungicide of the present invention.

I. Controlling Effects on Various Plant Diseases by Foliage Application (Pot Experiment)

Experimental Method

A test compound was dissolved in a small amount of N,N-dimethylformamide, and the solution was diluted to a given concentration with distilled water containing a spreader. Thus, a liquid sample to be tested was prepared. The liquid sample was sprayed to test plants, and 24 hours thereafter, pathogens were inoculated by the method described below.

The percent control was calculated according to the following equation: ##EQU1##

Test Example 1

Controlling Effect on Pyricularia oryzae

Two-week rice seedlings (cv.: AICHIASAHI) were transplanted in plastic cups (each 9 cm in diameter) and cultivated further 2 weeks. The test compound in the form of a solution or a suspension was sprayed to the foliage of the rice seedlings, to which a conidia suspension of Pyricularia oryzae cultured in an oatmeal medium was inoculated by spraying. After the inoculation, the test plant was kept in a moist chamber (28° C., 100% R.H.) for 24 hours, followed by cultivation in a greenhouse for 5 days. Six days after the inoculation, the number of lesions on the leaves of the inoculated plant was measured to calculate the percent control.

The results are as follows.

Test Example 2

Controlling Effect on Sphaerotheca fuliginea

Seeds of cucumber (cv.: TSUKUBASHIROIBO) were sown in plastic cups (each 9 cm in diameter), followed by cultivation for 2 to 3 weeks. The liquid test sample in the form of a solution or suspension was sprayed on the surface of their first leaves. The pathogen was inoculated to the leaves by spraying a conidia suspension of Sphaerotheca fuliginea which had been cultured on the cucumber leaves. After the inoculation, the plants were kept in a greenhouse at 20° C. for 10 days. Then, the infected area on the leaf was observed, and the percent control was calculated.

The results are as follows.

Test Example 3

Controlling Effect on Botrytis cinerea

The seeds of cucumber (cv.: TSUKUBASHIROIBO) were sown in plastic cups (each 9 cm in diameter), followed by cultivation for 2 to 3 weeks. The test compound in the form of a solution or suspension was sprayed to the surface of their first leaves, and mycelial disks (4 mm φ) of Botrytis cinerea cultured on the potato sucrose agar medium were put on the leaf surfaces to inoculate the cucumber seedlings with the pathogen. The plants were kept in a moist chamber at 20° C. for 3 days. The diameter of the lesions on the leaves was measured and the percent control was calculated.

The results were as follows.

Test Example 5

Controlling Effect on Puccinia coronata

The seeds of oat (cv.: PC-38) were sown in plastic cups (each 9 cm in diameter), followed by cultivation for 2 to 3 weeks. The test compound in the form of a solution or suspension was sprayed to the seedlings. Spores of Puccinia coronata cultured on oat leaves were collected, diluted about 10-fold with talc, and sprayed to the test plants to inoculate the plants with the pathogen. After the inoculation, the plants were kept in a moist chamber at 20° C. for 1 day and then in a greenhouse at 20° C. for 8 days. The infected area on the leaf was observed, and the percent control was calculated.

The results are as follows.

Test Example 6

Controlling Effect on Pseudoperonospora cubensis

The seeds of cucumber (var.: TSUKUBASHIROIBO) were sown in plastic cups (each 9 cm in diameter), followed by cultivation for 2 to 3 weeks. The test compound in the form of a solution or suspension was sprayed to the surface of their first leaves, and a zoosporangia suspension of Pseudoperonospora cubensis cultured on cucumber leaves was dropped on the above leaf surfaces to inoculate the test plants with the pathogen. After the inoculation, the plants were kept in a moist chamber at 20° C. for 10 days. Then, the area of the lesions around the inoculum were observed and the percent control was calculated.

The results are as follows.
